CP-115953
CP-115953 is an antitumor fluoroquinolone compound that targets eukaryotic topoisomerase II and Escherichia coli DNA gyrase. CP-115953 inhibits ATP hydrolysis and DNA relaxation by stimulating enzyme-mediated DNA cleavage, and enhances the expression of immune-related cytokines. CP-115953 is applicable for research on human cancers.
